why wasabi: update change avoidance to privacy suggestions

[MarnixCroes]

when change avoidance was added, we didn't have the privacy suggestions yet, so update it

[yahiheb]

Why removing the Change avoidance suggestion part?
I think we could keep it and add the Privacy suggestions separately.

[MarnixCroes]

Why removing the Change avoidance suggestion part?

because the change avoidance is a privacy suggestion

[yahiheb]

So because of that it should be removed as a solution to avoid change?

Does Privacy suggestions fit in this document about coins?

[MarnixCroes]

privacy suggestions are about coins:
don't select non-private coins, only select semi-private coins, private coins, don't have change coins, select coins of same label, selecting more than 10 coins, using coinjoining coins etc

[yahiheb]

But out of all those cases change avoidance stands out, and thus my suggestion to keep it and add the Privacy suggestions separately.
One other reason to keep it is to not break any external links unless really necessary.
